초록

Four crystal forms of cephradine were isolated by recrystallization and characterized by powder X-ray diffractometry, differential scanning calorimetry, and thermogravimetric analysis. The dissolution patterns of four crystal forms of cephradine were studied in water at $37{\pm}0.5^{\circ}C$, 90 rpm for 120 min. The amount dissolved at 120 min was highest for Form 1 ($100\%$), followed by Form 3 ($98.9\%$), Form 4 ($77.83\%$), and Form 2 ($75.55\%$). After storage for two months at $0\%$ RH (silica gel, $20^{\circ}C$), $52\%$ RH (saturated solution of $Na_{2}Cr_{2}O_{7}{\cdot}2H_{2}O/20^{\circ}C$), and $95\%$ RH (saturated solution of $Na_{2}HPO_{4}/20^{\circ}C$), none of the crystal forms showed transformation.
